Would edging-ballooning with a harder-firmer grip have better results

If the grip is harder, the penis would be “less sensitive” kind of thing, if you see what I mean?

I am not sure if it matters if you are referring to holding back ejaculation… I may be wrong though.

I don’t know about ballooning, but edging is just masturbating, up to the edge of cumming, but stopping just short. So from the edging side of it, use your best masturbation “grip”.

My understanding is ballooning is just another name for edging? Or am I mistaken?

I don’t think a hard grip is the point. The point is to bring yourself to high arousal levels for long periods of time in order to engorge the penis to its maximum level.

No, I don’t see what you mean. Are you getting manual clamping or uli’s confused with edging?

You can edge or balloon by running your finger up and down, there is no grip required. Try not to panic.
